Therail or guide the shaft, the same being suitably supported I by a suitable truss l3 orthe equivalent for the purpose. The bucket 8 is provided with a sloping bottom 15, and with a pivoted or hinged bottom 16, which is normally maintained closed by latches 18 on each side of the bucket, engaging the pins 17 on the hinged bottom. lhe bucket is provided with a bail, consisting of the side members 20, which are pivotally secured at 21 at both sides of the bucket and connected by a cross member 28, to which is secured the hoisting and operating cable 29. The bail members are provided with. flanged wheels'or rolls 22 and 26, arranged to travel between the rails 10 and 11 when the bucket is in the shaft. When the bucket is on the tracks 12 the wheels 22 carry a portion of the load, as hereafter described. To the 'bail members 20 are pivgtally secured links 23 connected by a bar 25, which has a cable 2 1 secured thereto, the opposite end of; which is connected to a similar bar on the other bucket, f-when twobuckets are used in the system. l/Vheh one bucket is used the cable is connected to cable 29, or is cable 29 extended.

Then the bucket is in the shaft it is carrierl by a sheave or pulley 30, over which the cable 29 passes. The sheave 30 is provided with an axle or shaft 31, which is carried by brackets 33 on the brackets 23% "when the bucket is in the shaft. Locking members 35, having hooked ends 45, normally lock the shaft 31 on the bracket Resilient members 38 normally maintain the locking members 35 in operative position. The locking members are keyed to the shaft 37, which is pivotall-y supported at 36. -Keyedto the shaft 37 is a bar 39, the opposite end of which is connected by a bar 40 to a lever ll, pivotally supported at 42. ()n the bucket is provided a hinged lid or extension 43, which is arranged to cooperate with the lever 41 to release shaft 31, when the upper end of the bail members 20 are interposed substantially as shown'in Fig. 2.

, Arranged to cooperate with the bucket and sheave 30 is a frame l hprovided with a pair of wheels 46, formed to coiiperate with the shaft 31 and bail members 20. The frame a l is extended at 47 arranged to .be supported by a bracket 52 when substantially positioned as shown in Fig. 2, with the notches 53 in line with the pins 27 and the notches 5O seated on pins or brackets 51. A

"locking member 54: is provided on one orboth sides of the frame and arranged to en,-

gage'pins 55 when the bucket is drawn later.

ally, a spring 56 maintaining the lock in position. When the bucket is in the shaft the locking members are maintained open by the pins 57 (see Fig. 2) the weight of the frame 4 1-47 being suliicicnt to overcome the tension of the springs 56.

As the bucket is raised the bail members pick up the shaft 31, the frame-part 47 being engaged by the pins 27, so that the shaft 31 and sheave 30 are carried by the two parts, substantially as shown by the dotted lines in Fig. 2, the frame and bail being locked together by the locking members 54. It will thus be seen that the bail, members 20 and the frame members 44%? form substantially a rigid. carriage supported on wheels 22 and 4:6, in which carriage the bucket 8 is carried, and propelled by the cable 29. It might be noted that the sheave and its axle or shaft 31 can be attached directly to theframe 44- 17, in which case the locking members, various supporting brackets, etc., might be omitted.

' The bucket is prevented from swinging while in the shaft by means of rails 60 and 61 spaced so as to permit the wheels 62 arranged on the bucket to travel between them. The rails 61 are-extended up to join the track rails 12, so as to guide and prevent swinging of the bucket until it is supported upon the tracks 12, after which swinging is prevented by the rails 63, between which "and the rails 12 the wheels 62 are positioned. Suitably positioned where desired over one orthe other of the bins are the trippers 65, providedwith rolls 66, which cotiperate with the latches 18 to disengage the same from the pin 1'1 to discharge the contents of the bucket. The stops 68 and 7 2 limit the movement of the tripping arms 65, which are normally maintained 'in position by the weights 67. As the bucket returns to the shaft the trippers tip to permit the latches 18 to pass (as indicated by the dotted lines). Positioned preferably where shown, near the mouth or top of the tracks, provided a closer for closing the bucket door or bottom 16. closed by the rolls 69 and completely closed by the resiliently supported rolls 70 hurried on the tripping arm 71, which are also preferably weighted as at 73, the same tipping to permit the loaded bucket to pass, but extending up so as to close the door on the return trip of the bucket- In the preferred construction, the discharge of the coal from the receiving bins or hoppers 5 into the buckets is controlled by the buckets, as will be more fullyfexplained hereafter. In. the drawings, I show love forms of'automatic measuring,- feeders As shown, the door is partially for controllingthe discharge of coal or loading of the buckets, either one to be adapted to be similarly controlled by the buckets.

150 (see Figs. 1, 2, 3 and 9) pivotally con-- nected or supported at 151 and secured to the cables 101, as at 102.. The number of controlling levers 150 and arrangement thereof may be varied, as will be more fully 1;he levers 150 are operated by the extensions 1 15 on the pivoted levers 145, pivotally secured to the frame 44 as at 146. (See Fig. 2.) 1n the form shown in Fig 2, 147 is the stop which limits the movement .of'the lever 1el5, so that as it is carried by the frame 4 1 it trips the lever 150 and throws it into the dotted position shown in Fig. 2. Under certain circumstances or conditions hereafter described, the stop is placed on the. opposite side, as for example 148 is extended and 1 17 omitted, so that the lever 150 is tripped when the bucket is going lllllle opposite direction. This will be more fully explained in the modified controlling systemsfor the The operation ofthe system may be described as follows The rotation of he drum D (referring to Fig. 9) is controlled by the switch 162, assuming the drum D to be electrically driven, or by equivalent means when other power is used, which is controlled by the cables 101 operated by the" tripping levers 166. The cable 29 which'i's operated the drum D is connected tothe bails 20 of the two buckets. The links 23 secured to the lower end of the bucket bails, are connected by a bar 25 to which is fastened cable 24. The feeder filling gates 92 and 02 (or 125-128?) are connectedby the cable 101, thetripping or operating levers being pro- I vided. The'feeder filling gates 92 [and 92 are also connected by cables 08 or their equivalents. Assuming for example. that the buckets are in the positions shown in Fig. 9, that the bucket 7 has discharged its load and reversed the drum D. and that bucket 8 is filled and is at the foot of the shaft. "111 this case gate 02 is shut andgate 92 open, while the feeder discharging gate 103 is open, as indicated by the dotted lines in Fi 4 afhd the feeder dischar 'in ate 103 for feeder bucket 7 is closed. As bucket 8 is hoisted .in the shaft, it closes gate 103 and, bucket 7 is drawn toward the fool of its shaft.

\Vhen'the-bucket 8 reaches the mouth of the shaft, the bail 20 picks up the shaft 31 and with the frame 1 1', the lock 35 having been raised, carries the sheave 30 and shaft 31 substantially as shown in the dotted'lines in Fig. 2, the'buckct traveling along the tracks toward the drum end of the track. As soon as the bucket starts up the shaft it closes its gate 10?. which is'automatically locked by the latchjlOS, and as the bucket travels along-inc track on the,

upper level 1t en ages It's lever 150 opening its own feederiilling gate 92 and at the eating time.closing feeder filling gate 92};

At the end of its travel the bucketengages the lever 100 and reverses the direction of rotation of the drum D. In the meantime the shaft 9 and opened its gate 103, so that the bucket is tilled. The trips 66 (see Fig. 2) for opening the buckets are placed where desired over the first or second bin. The levers 150 may of course be placed where desired, as for example in Fig. 0, they are shown near the extreme end of the tracks 12 while in Fig. 1 they are shown near the shaft. As the buckets return and before entering the shaft, the bottoms are closed by the rolls (it) and T0 and locked by the latches 18. In the system just shown and described. the lovers 150 are operated by the loaded bucket on its going trip. The

8 is substantially similar, the cables 101 representing the cables 101, so that as the buckets trip the lever 150 the slide 123 is inovcd to fill the different measuring hoppers in the same manner as the filling gates 02. The feeder discharge gates 128 are raised by the buckets engaging the extensions 134. system is substantially the same for controlling either form of measuring feeder.

Figs. 11 to v18 respectively represent forms of control for the feeder tilling'gates. In Fig. 11 the loaded bucket going, opens its hopper filling gate 92 and at the same time closes the filling gate 02 for the other bucket before reaching the end of its travel. If the trips 14:5 are changed so that the trips are engaged by the extension 14-8, and not by the extension 11-7. the empty bucket returning will close its filler feeding gate and at the same time open the other feeder filling gate before it reaches the bottomof the shaft. As illustrated in Fig. 12, the empty bucket closes its own hopper .filling gate 192 before reaching thebottom of the shaft, and at the same time opens the otherhoppcr filling gate 92. By changloaded bucket. opens ilshopper filling gate and at the same time closes the other gate 02 or by changing the trips as described, the empty bucket closes its own gate and opens the other gate. As illustrated, Fig. 13 is substantially similar to Fig. 11. As illustrated in Fig. 14, one bucket controls both feeder filling-gates, that is going it opens its own gate and in returning closes it, operating the other gate at the same time. in this case there is a trip 14-5 on each side, one operz-iting in one direction and the other in the opposite direction of the travel of the bucket. l ig. 15 illustrates the system in which the empty bucket closes its own gate in returning and in going up loaded opens it; or it may be said that the empty. bucket l opens the other get-e when the other bucket the bucket 7 has traveled to the bottom of operation of the gate shown in Figs. 5 and It will be seen therefore that the 15 go ng with i load, and when loaded closes the other V Fig. 16 illustrates the system-as appliedyl'o a single bucket and in the system shown in. Fig. 10, the 0011-,

l'rol is somewhat similar to that in the station described, the distinction being that in 29 this case cars are substituted for buckets, and the some are drawn up an incline so that the c is transferred both vertically and s in the other system. This form. s also applicable to a horizontally 'r'eling car and measuring feeder. Rel es ring to ihe figure, 170 represents inclined tracks, ll'l. lhc receiving bins which receive lhe coal from cars 172, or the equivalent, arranged on the trestle 172 above the receiv- 0 mg hoppers.
